5×20 mm Hızlı (Yavaş) Kurşunlu tüp sigortaları

The 520 fuse is a cylindrical glass or ceramic fuse tube with a diameter of 5mm and a length of 20mm. The rated voltage is usually 250V, and the current ranges from 0.1A to 30A.

There are two main types of 5*20 sigortalar: fast-blow type (F tipi) and slow-blow type (T tipi). Fast-blow type is suitable for general electronic equipment, while slow-blow type is suitable for equipment with large starting current such as motors. The current specifications are very wide, ranging from the smallest 0.1A to the largest 30A.

Uygulama senaryolarına ilişkin, bu tip sigorta ev aletlerinde yaygın olarak kullanılmaktadır, endüstriyel ekipman, Otomotiv Elektroniği ve Diğer Alanlar. Satın alırken dikkat edilmesi gereken parametreler arasında anma akımı yer alır., anma gerilimi, kaynaştırma özellikleri (hızlı veya yavaş), ve sertifikasyon standartları (UL gibi, CSA, VDE, vesaire.).

There are also different types of 5*20 sigorta tutucular, such as direct plug-in type, waterproof type with leads, and PCB mounting type. Waterproof fuse holders are suitable for harsh environments such as outdoor lighting. The current carrying capacity of the fuse holder is usually 6-10A, and can reach up to 30A.

5*20 fuse is a standard size (5mm çap, 20mm length) cylindrical circuit protection component, mainly used for overcurrent protection. The following is its core characteristics and application information:

BEN. Basic specifications and types
‌Size standard‌
Unified cylindrical design with a diameter of 5mm×length of 20mm, glass or ceramic package, and metal cap electrodes at both ends. ‌
"Cam tüp": transparent and visible, easy to observe the fuse status (common in low-voltage household appliances).
"Seramik tüp": strong high temperature resistance, suitable for industrial environments. ‌

‌Current and voltage range‌
‌Nominal gerilim‌: mainstream is 250V, and some models support 125V. ‌
‌Mevcut aralık‌: Covering ‌0.1A~30A‌, common segments include:
‌Small current‌ (≤1A): 0.1A, 0.2A, 0.25A, 0.5A, 1A (precision instruments, LED aydınlatma);
‌Medium and high current‌ (>1A): 2A, 3A, 5A, 10A, 15A, 20A, 30A (power supply equipment, motor);

‌Fusing characteristics‌ ‌Fast-break type (F tipi): Quick response, suitable for sensitive electronic equipment (marked such as F1A, F5A). ‌
Yavaş kırılan tip (T tipi): Resistant to instantaneous current shock, motorlar ve transformatörler için uygun (marked such as T2A, T10A). ‌

II. Key parameters and certifications ‌

Electrical performance‌ ‌Breaking capacity‌: 35A@250V (low current model) to 200A@250V (high current model), kısa devre durumunda güvenli bağlantı kesmenin sağlanması. ‌
‌Sıcaklığa uyum sağlama‌: Working temperature ‌-55℃~125℃‌, passed the hot and cold shock test (-40℃~90℃ cycle). ‌

‌Safety certification‌
Mainstream products have passed ‌UL, CSA, CCC, VDE, RoHS‌ certification and meet international safety standards. ‌

🛠️ III. Application scenarios and accessories ‌Typical applications‌
‌ Househhold Cihazlar‌: power adapter, small appliance circuit board (commonly used 1A~5A). ‌
"Endüstriyel ekipman": servo sürücü, güç modülü (commonly used 10A~30A). ‌
‌Outdoor equipment‌: su geçirmez sigorta tutucu (IP67 sınıfı) for street lights and vehicle-mounted equipment. ‌

‌Eşleşen sigorta tutucusu‌
‌PCB kurulum türü‌: straight leg/bent leg design (such as PTF-77), supporting 10A~20A current. ‌
‌Waterproof lead type‌: with PVC sheath and nickel-plated brass terminals (H3-520E gibi), suitable for harsh environments. ‌

💡 IV. Purchase recommendations ‌Current matching‌
Select according to 1.5 times the maximum operating current of the circuit (Örneğin: the maximum current of the circuit is 2A → select a 3A fuse). ‌
‌Motor type‌: Prefer slow-break type (T) to avoid false fuse at startup. ‌Digital circuit‌: Select fast-break type (F) to enhance overcurrent response. ‌
‌Certification and reliability‌
Confirm that the product has the ‌UL/CCC‌ mark to avoid uncertified brands (high safety risks). ‌

‌Purchase channels‌
Bulk purchase: Yaxun Elektronik’ 1688 platform ($0.02/parça, 100 minimum adet) ‌
Retail replacement: Yaxun Elektronik’ JD/Tmall (hakkında $0.5 için 10 pieces). ‌

💎 Özet
5*20 fuse is the basic protection component of electronic circuits. The selection needs to be based on current demand, fusing characteristics and environmental conditions. Give priority to brand products with complete certifications (such as Litte and Huade), and match them with corresponding fuse holders to ensure stable installation. ‌ For industrial or outdoor scenes, be sure to choose waterproof and high temperature resistant models to ensure long-term reliability.
